DevFS.update only runs in Dart 2 mode when the generator parameter is
supplied. In Dart 2 mode, both mainPath and pathToReload are required
parameters; this patch marks them as such.

generator is required for running in Dart 2. All call sites other than tests already explicitly set this value.

Note the statements on line 510 and line 516 for why mainPath and pathToReload are required.

Its type uses a generic type which is limited to library-visibility.
Eliminating compilationQueue from ResidentCompiler's public interface
makes it possible to mock in tests.

This fixes https://github.com/flutter/flutter/issues/20746

https://github.com/flutter/flutter/issues/19578

Flutter commands all default to --preview-dart-2. Eliminate support for
the use of this option and the previewDart2 parameter in dev/devicelab
tests.

Normalize file path to non-Windows so string path comparison works.

Clarify the intent of these tests.

* Pass uri instead of filepaths when hot-reloading.

Bug: https://github.com/flutter/flutter/issues/21168

* Remove imports. Enable another test

* Restore skipping of test on mac

This adds links to the already existing animated diagrams in the asset-for-api-docs repo.

* Split analysis steps out of dev/bots/test.dart into dev/bots/analyze.dart.

This allows to run analysis step with command line arguments that are only applicable to flutter analyze(like --dart-sdk, needed for dart-flutter-engine head-head-head bot).

* Add forgotten dev/bots/analyze.dart

* Refactor common code from analyze.dart and test.dart into run_command.dart

* Remove comments, add header

* [FAB] Updated tooltip touch target.

* Remove "new" keyword

* [FAB] Updated tooltip touch target.

* "long press button edge"

* remove new

* remove new

* put "new" keywords back in

* Remove check for childless tooltip

* Added regression test - tooltip works on edge of FAB which has no child.

Added helper method to find the right edge of a in the tests.

* Changed "find.byType(text)" to "find.text('Add')"

When switching between channels, we were leaving around the version freshness stamp file (bin/cache/flutter_version_check.stamp), which meant that the flutter tool would read from that file to see what the cached date of the most recent commit to the current channel (branch) was. The problem was that since the file was created while on the previous channel, the cached date was for the wrong channel, so if you switch from master to beta, flutter would think that the channel was out of date, and a new version was available, at least for three days after the first time it checked (after three days since the last time the freshness was checked, the cached date would get updated).

This PR modifies the channel command to remove that stamp file whenever the user switches channels, so that the cached date will be from the right channel when it is recreated.

Fixes #21134

This is a bit of a stab in the dark for a flake sometimes seen on bots (but I can't repro locally) #20822. Detaching from a Flutter app currently seems to terminate it, so it may be the cause of the "app not found" when trying to stop the app subsequently.

This change means we stop the app from the main process first, before terminating the attach process.
